Relationships 👩❤️👨 Flashcards
Sexual selection
Evolutionary explanation for sexual partner preferences. Attributes that increase reproduction are passed through generations
Anisogamy
Differences between male and female gametes (sex cells)
Sperm vs egg
Mobility
Size
Quantity
Amount of time produced for
Energy expenditure
Inter sexual selection
Preferred by females
Quality over quantity
More choosy as they have less gametes
Want fit males who can provide
Intra sexual selection
Preferred by males
Quantity over quality
Dimorphism- men are bigger than women
Want as many fertile females as possible
Attractive body shapes
Men want hourglass, women want big and broad shoulders
Evaluations of sexual selection
Strength anisogamy - research support, Buss, surveys 10,000 adults and found men cared more about looks and age when women cared more for assets
Strength - inter sexual selection, Clark and Hatfield, uni students “Will you sleep with me”, 75% of men said yes, no women said yes
Weakness - ignored social and cultural influences, Bereczkei et al suggested women are no longer reliant on men as they can work
Weakness - more complex, Penton Voak et al said women’s preferences change over the menstrual cycle
Self disclosure
Revealing personal information about yourself, relationship formation is built on trust with another person. Leads to greater intimacy and satisfaction
Social penetration theory
Altman and Taylor, gradual process of revealing your inner self to someone
Breadth and depth
As both increase partners become more committed (onion)
Reciprocity
Reis and Shaver, other should respond with their own personal thoughts. Balance of self disclosure increases intimacy
Evaluations of self disclosure
Strength - research support, Sprecher and Hendricks studied straight couples and found correlations between self disclosure and satisfaction
Laurenceau found higher levels of intimacy with self disclosure
Weakness - correlation vs causation
Weakness - culture bias. Tang et al found more shared sexual thoughts in USA compared to china
Importance of physical attractiveness
Shackelford and Larson found that peoples with symmetrical faces are more attractive (honest signal of good genetics)
Baby faces are attractive sure to look of caring and protective instincts
The halo effect
Where one feature has a disproportionate influence on our judgement of other features
Dion et al found that attractive people were rated as kind, strong, sociable and successful
Evaluations of physical attractiveness
Strength - research support halo effect, Palmer and Peterson physically attractive people were rated as more politically knowledgeable
Strength - research support matching hypothesis Feingold meta analysis of 17 studies, correlation between attractiveness in romantic partners
Weakness- complex matching, Precher and Hatfield, poor evidence due to other attractive attributes
Filter theory
Kerckhoff and Davis studied student couples, three filters social demography, similarity in attitudes and complimentarity
Evaluations of filter theory
Strength - research support, winch
it has face validity as it expresses most people’s relationships, Winch found that these filters were important in beginning and complimentarty long term
Weakness - failure to replicate, Levenger said it’s difficult to define depth of relationship in length. They said cut off point for short term relationships was 18 months but this doesn’t apply to all
Weakness - culture bias, some collectivist cultures have things like arranged marriages, this only applies to individualist cultures
Social exchange theory
Thibault and Kelley
Economic
Commitment dependent on profit
Rewards should outweigh costs
Comparison level
Judge whether someone’s worth being in relationship with
Use past experiences
Amount of reward you think you deserve
Link with self esteem
Comparison level for alternatives
Someone weighs up potential increase of rewards from a potential new partner
Stages of relationship development
Sampling stage - explore costs and rewards
Bargaining stage - exchanging costs/rewards
Commitment stage - costs/rewards predictable, more stable
Institutionalisation stage - partners settled
Evaluations of social exchange theory
Strength - research support, Sprecher longitudinal study, 101 couples in US found CLalt was strong predictor of relationship success
Weakness - cause and effect Argyle argues people are dissatisfied which causes CLalt
Weakness - reductionism, limits range of real life relationships why do people stay in abusive relationships
Equity theory
Walter et al
Economic
Both partners profit should be the same
Ratio
Lack of equity
Inequity causes the under benefited partner to feel anger resentment and hostility whereas the other feels guilt shame and discomfort
Dealing with inequity
Revise perception of costs and rewards and change accordingly
What once was a cost now feels like a norm
